问题描述

是否可以使用Playground中的animateWithDuration预览为UIView完成的动画？我在UIView初始化之后立即添加了XCPShowView，无论我在时间轴上选择什么位置，它都会显示它处于最终状态。

Is it possible to preview animation done for UIView with animateWithDuration in Playground? I am adding XCPShowView right after initialization of UIView and its shows everything it in a final state no matter what position on a timeline I will choose.

推荐答案

Xcode 7更新： XCPShowView 已被弃用，但你可以看到动画在操场上liveView。还有更多内容即将推出：

Xcode 7 update : XCPShowView is deprecated but you can see the animation in the playground liveView. And there is more coming soon: Interactive Playgrounds

这是Joseph Chen示例代码的更新。我还将颜色更改为绿色，因为容器默认背景为黑色：

Here is an update to Joseph Chen sample code. I also changed the color to green as the container default background is black :

import UIKit
import XCPlayground

let container = UIView(frame: CGRect(x: 0.0, y: 0.0, width: 100.0, height: 100.0))
// XCPShowView("container", view: container)  // -> deprecated

let view = UIView(frame: CGRect(x: 0.0, y: 0.0, width: 50.0, height: 50.0))
view.backgroundColor = UIColor.greenColor()
container.addSubview(view)

UIView.animateWithDuration(5) {
    view.center = CGPoint(x: 75.0, y: 75.0)
}

XCPlaygroundPage.currentPage.liveView=container
